Fumigant compositions including hexafluoropropene or 1,1,3,3,3-pentafluoropropene, and methods of making such compositions, are provided herein. The fumigant compositions may be suitable for use as soil fumigant compositions and structural fumigant compositions against a variety of undesirable species such as weeds, nematodes, pathogens, animals and insects. The fumigant compositions also have low toxicity and low Global Warming Potential. In one embodiment, a fumigant composition includes hexafluoropropene, 1,1,3,3,3-pentafluoropropene or a combination thereof. The fumigant composition further includes at least one component selected from methyl iodide, chloropicrin, acrolein, 1,3 dichloropropene, dimethyl disulfide, furfural, propylene oxide metham sodium and combinations thereof. The fumigant composition also includes at least one surfactant. |
